DC Road Closures Today
How to check Washington DC road closures, construction projects, and event-based street closures — fastest sources, official DDOT channels, and what affects school commutes.
Quick Answer
The DC Department of Transportation (DDOT) publishes real-time closures at ddot.dc.gov/page/traffic-and-construction. For breaking incidents, follow @DDOTDC on Twitter/X and WTOP Traffic. Waze and Google Maps ingest DDOT data and auto-reroute. For emergency closures call 311; for active incidents call 911.
Where to get DC road closure alerts
The fastest official source is @DDOTDC on Twitter/X and the DDOT closure map. For rush-hour and breaking incidents, WTOP Traffic is the most-cited local source. Sign up for AlertDC for DC-government emergency notifications including major closures.
Who decides DC road closures
The District Department of Transportation (DDOT) is the primary authority for DC street closures, construction permits, and event permits. DDOT manages all DC-controlled roads, sidewalks, streetlights, parking, and transportation policy.
Federal park roads — Rock Creek Parkway, GW Parkway, the National Mall, and the Tidal Basin loop — are managed by the National Park Service (NPS). Major event closures (Marathon, Cherry Blossom, Independence Day, Inauguration) are coordinated between DDOT, MPD, US Park Police, and the Secret Service.
Emergency closures — water main breaks, downed trees, gas leaks, active police incidents — are triggered by MPD or DC Water with immediate DDOT signage and reroute coordination. Report non-emergency closures (potholes, broken signals, missing signs) via 311 or the DC311 app.
Recurring DC closures & events
These closures happen on a predictable schedule. DDOT publishes detailed closure maps 1–2 weeks before each event.

How DC road closures affect school commutes
Major event closures (Marathon, Cherry Blossom, Independence Day, Inauguration) can affect DCPS bus routes and after-school activity logistics, especially for schools in NW DC near the National Mall. DCPS Transportation issues bus-route advisories 1–2 weeks before scheduled events.
For unplanned closures during the school day — motorcades, water main breaks, police activity — DCPS reroutes affected buses in real time and notifies parents via the DCPS app and individual school emails. Most schools maintain a backup pick-up location for severe disruptions.
Families using Metro should also check wmata.com for parallel bus and rail closures — surface-street closures often coincide with Metro single-tracking or station closures during the same events.
